Application filed August 15, 1925. Serial No. 50,43?.

This invention relates to certain improvements in churns and it is an object of the invention to provide a device of this kind embodying a dasher which operates in connection with a churn of any desired type to effect the requisite churning operation.

Another object ofthe invention is to provide a device of this kind Comprising a dasher supported for rotary movement to gether with means operating during the rotation of the dasher to effect a further agitation of the material.

An additional object of the invention is to provide a device of this kind embodying means whereby during the operation of the dasher, a current of air is directed upon the material being agitated, such air blast serving to maintain said material cool and at the same time to keep off dust, flies and the like.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved churn whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawing, wherein Figure 1 is a view in side elevation with a portion broken away of a churn constructed in accordance with an embodiment of my invention, the coacting receptacle be.- ing diagrammatically indicated by broken. lines;

Figure 2 is a view in front elevation of the dasher proper as disclosed in Figure 1, unapplied. 7

As disclosed in the accompanying drawings, S denotes a supporting member and which supports at its upper portion a gear 1 adapted to be driven by the hand crank 2 or otherwise as may be desired. The gear 1 is in driving connection through the medium of the pinion 3 with a vertically disposed shaft 4 depending from he upper por tion of the member S and above the table or platform 5 carried by the supporting member S.

Pivotally connected by the coupling member 6 to the lower portion of the shaft a is the'upper portion of the stem 7 of the dasher D, said dasher as herein disclosed being substantially in the form of an inverted. U. v

Extending between the lower or free end portions of the side members or arms 8 of the dasher D is an elongated agitating men her 9 of material width the central portion of said member 9 being pivotally connected through the mediumof the pin 10 or the like with said free extremities of the side members or arms 8. One face, as a, of the member 9 is substantially flat and is adapted to be disposed outermost when my improved device is employed with a fiat bottom con.- tainer while the opposite face Z) of the memher 9 is disposed longitudinally on a predetermined curvature and is adapted to be disposed outermost when the device is employed with a rounded bottom container or receptacle R as diagrammatically indicated by broken lines in Figure 1. The side mem bers or arms 8 of the dasher D are of such length to readily permit the desired reversal of the member 9.

My improved device may be employed in connection with any type of receptacle or container and does not require any special.

form of churn body and it has been demonstrated in actual practice that my improved structure can be employed to advantage in producing butter within a short poriedof time either from fresh or ripened cream.

As the dasher D is rotating within the receptacle R, the member 9 will oscillate or vibrate about its pivot 10 in a direction lengthwise of such dasher, thereby impart ing further agitation to the material resulting in a quick and effective churning action.

I find it of advantage and importance to attach to the inner portion of the stem 7 immediatelyadjacent to the dasher D proper a blade B disposed on a predetermined upward and inward incline and extending beyond the opposite sides of the stem 7. The inclination of the blade B is such to create a blast of air toward the receptacle R during the rotation of the dasher D, said blast of air operating to coolthe cream during the churning operation and to keep off dust, flies and the like.

From the foregoing description it is thought to be obvious that a churn constructed in accordance with my invention is particularly well adapted for use by reason i of the convenience and facility. with which susceptible of some change and modification it may be assembled and operated, and it will also be obvious that my invention is without departing from the principles and. spirit thereof and for this reason I do not wish to be understood as limiting; myself. to the precise arrangement and formation of the several parts herein shown in carrying out my invetnion in practice except as here inafter claimed.

I claim 1.As a new article of manufacture, a churn dasher and an agitating member pivotally supported bythe dasher for rocking movement in a direction lengthwise of the ,dasher, said agitating member being of mathe member being substantially fiat and the opposite face being disposed longitudinally on a curvature.

2. As anew article of manufacture, a daslier substantiallyin the form of an inverted U and provided with a stem extending from the upper portion thereof and an agitating, -member pivotally supported between the tree extremities of the dasher,

- said agitating-member beingotwmaterial signature.
